ADJUSTER FOR ELECTRIC-LIGl-ET GORDS OR CABLES.

Application filed November 12, 1907.

movable from a cord already in position without disturbing or removingthe cord liXt-ures or iastenings. etliciently operative in any positionof the adjuster, and which will attord at all times opportunity toinspect the cord or cable without removal of the adjuster. These objectsl attain by the novel construction. combination and arrangement oi partshereinafter described, and shown in the accoiupanyiug drawings. inwhicln- Figure 1 is a front elevation of my adjuster. Fig. is a sideelevation of the same. Fig. 3 is tront elevation showing the adjusteroperatively applied to an electric light cord or cable.

Similar reference letters indicate like parts throughout the drawings.

A represents the body of my adjuster which is provided with a centrallylocated channel way A extending entirely across said body and open onits front and at each end. and having its side walls disposed inconverging planes. and each side wall provided witl a concave channel orgroove, (1, in diately disposed in said wall and extendinglongitudinally thereof. The ends of said side walls are rounded and saidgroove carried through such rounded end in order to prevent injury tothe cord or its insulation. B represents a wedge-shaped binding-memberarranged and adapted to be seated and operatively slidable in saidchannel-way A The side walls of said member B are disposed in convergingplanes and are each pr vided with a mediately located longitudinallydirected groove, as 2), arranged and adapted. when said member isopcratively seated in said channel-way, A to register with the groove inthe contiguous side all of said channel way, and in conjunctiontherewith constitute a duct or passageway for the electric light cord orcable passed therethrough. Said member B is Specification of LettersEPatent.

provided with a mediately located oblong aperture. o", and a screw 5, orother :tastening means, passed through said aperture and into the body Athereunder, serves to hold said member ii in operative position in saidchannel A and also to limit its reciprocating movements in eitherdirection. Said binding-member l) is slid backward in said channel A toafford opportunity to easily insert the cord by passing the end throughone duct and back through the other in such manner that the bight of thecord will lie around the wider end of the member B, changing with easybends from a perpendicular to a horizontal position and back to itsfinal perpendicular position to connect with the lamp socket. (Fig.

in cases where it is desirable to apply the adjuster to a cord alreadyinstalled and it is not desirable to remove or disturb the connections.the biriding-member ii is bodily removedfrom the channel A. onwitlnlrawiug the screw s. or other fastening means. the cord placed inthe channel A with its bight or loop extending beyond the wider openingof said channel, the member B inserted between the parallel runs of thecord and reglaced in the channel A and the screw 5 replaced. The cordwill then be held in the juxtaposed grooves of the meiuber B and channelA as shown in Fig. 3, and strain on the cord will torce the member Btightly between the side walls of said channel. and the adjuster thussecured on the cord.

To shift the position of the adjuster on the cord to shorten or lengthenthe latter, or for purposes of inspection of the cord, ten sion appliedon the cord in the direction of the bight or loop will cause the member1 to slide backward out of the channel A until stopped by the screw 8.The cord will thus be released and mzj be readily inspected or theadjuster may be moved to another position on the cord. as the case maybe, and the member B then forced into its clamping position. (Fig. 3.)The weight of the lamp and socket will be sutlicicnt to hold the bindingmember clamped in the channel A I claim as my invention and desire tosecure by Letters Patent:

fin adjuster for electric light cord or cable consisting oi a bodymen'iber provided with a centrally located channel way extendingentirely across said body and open on its front throughout its length,and hav ing its side Walls disposed in converging planes, and each saidside Wall provided with a mediately disposed groove extendinglongitudinally thereof, a Wedge-shaped binding member adapted to beremovably seated in said channelway for limited reciprocating movementtherein, and provided With a mediately located longitudinally directedoblong aperture, and with a longitudinally directed groove mediatelylocated in each side Wall and arranged and adapted to register with thegroove in the contiguone wall of said chairoeiway when said and adaptedto hold said binding-1nember 20 in said channelivav and permit limitedreciprocating movement of said bindingmember therein.
